Cook with Android_ASTC? ASTCClient? pak, apk, and obb files

I am just trying to use the UE 5.4 Project Launcher to build my architecture project from UE 5.4.4 to my Quest 3. Should I choose Android_ASTC, or the Android_ASTCClient version?

I've successfully completed a build and it created pak file. I also have the apk file and obb file.

What do I do with these? What are the purposes of these files?

I tried deploying to device and it put it on my Q3, but seems to get hung up loading.
